William de Taillebois

William De Taillebois

William de Lancaster I, or William Fitz Gilbert, was a nobleman of the 12th century in Northwest England. According to a document some generations later, he was also referred to as William de Tailboys (de Taillebois) when younger. He is the first person of whom there is any record to bear the name of Lancaster and pass it on to his descendants as a family name. He died in about 1170.
